I think its more likey that founders, gurus, etc all have a natural way of attracting followers. A speaker, for example, probably attracts many followers from speaking engagements. I don't think the presence of the word speaker on that person's profile has a great effect on follows.

In my humble opinion, the middle questions in green probably tell you the most about a potential SEO. You can use those to tell where an SEO has been and also how much potential she has to grow in the future.
